Hey...last year I got Annapolis rigging to make up a "kit".... they've done alot of the bars and have a section of mast to work it. He sent me off with everything to do the job, rivets and all. My rigger in the Virgin Islands did the work with the mast up and the boat on a mooring... can't be that difficult. And surprise, I had no cracking/ stretching of the holes in the mast... but the stainless T fitting for the spreaders was cracking nicely.
